If your stuggling getting the spiritbinder 25 HC down, here is an expoit to make it very easy.
When you start the boss, 2 walls come up to stop you leaving his circle.
However, if you stack your raid outside where you pull him from, as long as you dont go too far up the ramp, you can fight him here and it has the effect of removing all mechanics from the fight except for the voodoo dolls.
This means no need to use the totems, no need to go in to kill spirits etc. It also means your dps can faceroll the boss ultra hardcore, effectively removing both the soft enrage, and enrage timers.
Enjoy
Heres where you should stack
Go get them kills! (Buy use at your own risk, after the LFR debacle)
